Specification of Letters Patent.

Patented Nov. 16, 1915.

Application filed September 8, 1914. Serial No. 860,690.

To all whom it may concern:

Be it known that I, JOHN J. RANDALL, a citizen of the United States,residing at Butte, in the county of Silverbow and State of Montana, haveinvented certain new and useful Improvements in Spring-Heels; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to spring heels for boots and shoes, and one ofthe principal ob jects of the invention is to provide a spring heelcomprising two telescopic members preferably made of sheet metal stampedinto form and provided with an interior spring and said heel adapted tobe connected to a boot or shoe so that when the wearer steps upon theheel it will yield and absorb the shocks and jars of the shoe cominginto contact with the pavement or concrete.

Another object of the invention is to provide a metal shoe heel of twotelescopic members containing a spring, said spring being substantiallythe shape of the inside of the telescopic member, and said spring beingconnected at one end to one of the members and at the opposite end tothe other member so that it will yield when the weight of the wearer ofthe shoe presses upon the front member of the heel.

Ihe foregoing and other objects may be attained by means of theconstruction illustrated in the accompanying drawing, in which,

Figure l is a longitudinal section through the sole portion of a shoeand showing a heel connected thereto and made in accordance with thisinvention, and Fig. 2 is a horizontal sectional view taken on the line22 of Fig. 1.

Referring to the drawing, the numeral 1 designates the sole of a boot orshoe and 2 is the inner sole thereof, while 3 is the counter of theshoe. Connected to the sole 1 of the boot or shoe by means of suitablecountersunk screws or rivets 4 is the upper metal heel section 5,preferably made in the form of an ordinary shoe heel and being hollow,as shown. The telescopic cushion member 6 of the heel is fitted withinthe member 5, and has a telescopic movement therein, the two membersbeing fitted together to slide freely but to form a smooth connectionbetween the two members so as not to admit snow or dirt into eithersection. Connected to the inner wall 5 of the section 5 is a spring 7,said spring at its upper end being connected by rivets 8 along thebreast line of the heel and said spring being inclined and secured at 9by suitable rivets or fastenings to the rear curved heel portion of thetread member 6, as shown more clearly in Fig. 1. When the heel is thusattached to a boot or shoe, the weight of the wearer will bear down uponthe telescopic member 6 and the spring 7 will yield sufliciently toabsorb the ordinary shock and jars incident to walking. A shoe heel ofthe character described will not be liable to wear away upon one sideowing to the yielding character of the same, and the heel may be readilyconnected to any shoe or boot, and when worn out may be readily renewed.

Various changes may be made in the details of construction withoutdeparting from the spirit and scope of the invention as defined in theclaim.

What is claimed is A spring heel comprising an upper sheet metal hollowmember having side and end walls, a lower sheet metal hollow treadmember having side and end walls, said lower tread member being arrangedto telescope in said upper member, and a spring substantially of theshape of the members when viewed in plan, said spring arranged to beplaced between said telescoping members and to be attached at the'lowerend portion of one member and at the diagonally opposite end portion ofthe other member.

In testimony whereof I afix my signature in presence of two witnesses.
